This is an entertainingly offbeat little comedy that took some chances both with the material and with the then-new capacity of sound in the movies. Robert Benchley's imaginative writing is complemented by his equally imaginative ideas for using visuals and sound, and the result is a short feature that is quite good for the early sound era.
Benchley plays a lecturer visiting a Ladies Club, the kind of role that usually brought out the best in him, since it allows him to use a dryly amusing style that fits well with his writing. Here, the weird topic is a particularly suitable choice for Benchley's writing and speaking. The 'lecturer' also moves back-and-forth between his lectern and a display screen that shows moving pictures of his lab specimens. It's interesting both in creatively using the format and in recreating (and satirizing) the way that a thorough lecturer might well approach the subject.
Benchley's jokes and gag ideas rarely if ever try for the big laugh. Instead, he tries to build up a comic effect through the accumulation of dry and ironic comments or visuals. This is a case where it works very well, and especially so given the limited resources and experience of film-makers in the early sound era.
